Re: clone3: allow creation of time namespace with offset

With Arnd's idea of only using nanoseconds, timens_offset would then
contain something like this:

struct timens_offset {
        __aligned_s64 monotonic_offset_ns;
        __aligned_s64 boottime_offset_ns;
};

I kind of prefer adding boottime and monotonic directly to struct clone_args

        __aligned_u64 tls;
        __aligned_u64 set_tid;
        __aligned_u64 set_tid_size;
+       __aligned_s64 monotonic_offset_ns;
+       __aligned_s64 boottime_offset_ns;
 };

I would also prefer the second approach using two 64-bit integers
instead of a pointer, as it keeps the interface simpler to implement
and simpler to interpret by other tools.
